I am a frist-year PhD student in the LIESMARS, Wuhan University. My advisors are Prof. Zhen Dong and Prof. Bisheng Yang. Previously, I obtained my B.Eng degree at SGG of Wuhan University.

My research interest lies in the field of 3D Computer Vision, particularly including point cloud enhancement (upsampling, denoising, completion , etc), 3D shape restoration. Besides, I am conducting some researches related to urban sustainable development. If you are interested in my research, feel free to contact me at chenlong107@whu.edu.cn!

I am a member of WHU-USI3DV, please check advancements on point cloud processing including enhancement, registration, localization, segmentation, detection, etc.
